Integrated marketing and technology services firm SapientNitro has developed a new augmented reality health app. ‘Lungs‘ uses a computer webcam or smartphone camera to superimpose medically correct digital lungs over the person’s image. Sliders on the edge of the screen allow you to input data, such as how many cigarettes you smoke a day and how many years you have smoked, which is then used to generate a representation of what your lungs look like. Medical experts were consulted to create an accurate depiction of the varying degrees of visual lung damage. A non-smoker would see lungs that are healthy and pink, whereas someone who had smoked a lot over a long period of time would see all of the damage and discoloration their smoking had caused.
